Simon,

I think that's kind of your choice, I'm using it for a Delphi XM radio unit, but I think the company designed them to be fairly flexible in their application. The part of the mount that extends from the dash has several holes in it so I guess you could either screw something in there or just use the belt clip attachment on your cellphone.

Keep in mind these things are very basic, it's really $30.00 for a piece of bent finished metal. But, they do serve their purpose nicely in the way they integrate into your dash. I think the link Analog posted above to the company's instruction page demonstrates what I mean.

By the way Randy, I didn't mean to hijack your post I was just trying to share what I though was a useful item.
